There was a time when companies providing flow assurance engineering services to the oil and gas industries used to find cost of license of OLGA software package prohibitively expensive. OLGA is the most popular software package for performing steady state and transient modelling of multiphase fluid in pipelines. There are other software packages available in the industry such as Ledaflow, Pipenet, Pipeline Studio and Maximus. However, OLGA still enjoys the monopoly and other software packages struggle to find favour amongst oil and gas companies. As a result OLGA charges premium for the license of the software. The cost of yearly license was so high that it was not cost effective for small companies to procure licenses. Recently Schlumberger has come up with a more cost effective and user friendly option for the industry and provides Cloud based environment called DELFI which provides access to OLGA and all associated packages such as Multiflash, Pipesim, OLGA Hydrate, OLGA Wax, OLGA corrosion etc. on a monthly subscription basis in combination with hourly rate payable for running OLGA.  This has helped smaller companies to deliver small projects at a reasonable license cost.
